Please provide values below to convert parsec [pc] to megaparsec [Mpc], or Convert megaparsec to parsec.
How to Convert Parsec to Megaparsec
1 pc = 1e-06 Mpc
Example: convert 15 pc to Mpc:
15 pc = 15 × 1e-06 Mpc = 1.5e-05 Mpc

Parsec
A parsec is a unit of length used to measure the large distances to astronomical objects outside the Solar System, approximately equal to 3.26 light-years. It is the distance at which one astronomical unit subtends an angle of one arcsecond.
History/Origin
The term "parsec" is a portmanteau of "parallax" and "second," coined by British astronomer Herbert Hall Turner in 1913.
Current Use
The parsec is the preferred unit of distance in astronomy and astrophysics for expressing the distances to stars and galaxies.
Megaparsec
A megaparsec is a unit of distance used in astronomy, equal to one million parsecs.
History/Origin
The parsec was first coined by British astronomer Herbert Hall Turner in 1913. The megaparsec came into use as astronomical distance measurements extended to other galaxies.
Current Use
The megaparsec is used to measure the distances between neighboring galaxies and galaxy clusters.
